The centered viewfinder and sizable handgrip make balancing a big lens a bit more pleasant. Others put the EVF in the corner, similar to the position of an optical finder in a rangefinder camera, and typically offer a smaller handgrip.Īs a general rule of thumb, an SLR-style camera is a better fit for use with larger lenses. Some are shaped much like SLRs, with an electronic viewfinder centered behind the lens mount. While most DSLRs are similar in size and build, mirrorless cameras are more varied in design. It's very important to choose a camera that feels comfortable in your hands. Some are designed to be used with APS-C sensors, and either won't work at all with a full-frame body, or will work, but with reduced resolution. If you see yourself moving up to a full frame in the future, be careful in buying lenses. These full-frame cameras are generally more expensive than their APS-C counterparts. Some cameras feature sensors that are equal in size to 35mm film. This allows more natural-looking images with a greater sense of depth. ![]() An advantage to the larger surface area is that changes in color or brightness are more gradual than that of a point-and-shoot. These larger pixels allow the sensor to be set at a higher sensitivity, measured numerically as ISO, without creating as much image noise. A 24MP APS-C sensor has much larger pixels than a point-and-shoot of comparable resolution. A lens with a maximum aperture of f/1.4 lets in eight times as much light as one of f/4, and can create a shallower depth of field at an equivalent focal length and shooting distance.Īnother reason to go for the big sensor is to minimize image noise. Much has been written about the quality of the bokeh created by different lenses, but the general rule of thumb is that the more light a lens can capture-measured numerically as its aperture, or f-number-the blurrier the background can be. This blur is often referred to by the Japanese term bokeh. It allows you to better control the depth of field in images, making it possible to isolate your subject and create a blurred background. There are many inherent advantages to a larger sensor. And even though the format is smaller than APS-C, it is significantly larger than a smartphone or point-and-shoot image sensor. Micro Four Thirds is the oldest mirrorless system, so there are plenty of lenses available. Its kit lenses are typically around 14-42mm in design, but don't give you a wider view than an 18-55mm APS-C lens. Micro Four Thirds, which has a 2x crop factor, is another popular mirrorless format, with cameras available from Olympus and Panasonic. ![]() This means that the 18-55mm kit lens that is bundled with most DSLRs covers a 35mm field of view equivalent to 27-82.5mm. The standard APS-C sensor features a "crop factor" of 1.5x. This can be a bit confusing when talking about a camera's field of view, as focal lengths for compacts are often expressed in terms of 35mm equivalency. Most consumer ILCs use image sensors that, while much larger than those found in point-and-shoot cameras, are somewhat smaller than a 35mm film frame. When moving beyond entry-level, SLRs catch up to mirrorless in capability quickly, and typically offer a larger library of lenses and accessories from which to choose-although it's mainly in exotic, very expensive options offered by Canon and Nikon that the wider selection comes into play. If your eyesight isn't perfect, an optical viewfinder may prove to be a better match rather than an electronic one, you may simply prefer their familiar feel, or you may already have access to compatible lenses.
